Ostarine / MK-2866 : Muscle Preservation

Ostarine (MK-2866) is a Selective Androgen Receptor Modulator (SARM) developed for muscle preservation, fat loss, and performance enhancement. Unlike anabolic steroids, it selectively targets muscle and bone tissues with fewer side effects, making it popular among athletes and bodybuilders.

  • Muscle Growth & Preservation: Increases lean muscle mass by stimulating protein synthesis, with studies showing 3–6 lbs (1.5–3 kg) of muscle gain in 8–12 weeks. Effective for preventing muscle wasting in conditions like cancer or HIV.

  • Fat Loss & Body Recomposition: Enhances insulin sensitivity, helping burn fat while preserving muscle during calorie deficits. Users report visible fat reduction, especially around the abdomen, without water retention.

  • Strength & Endurance Boost: Improves workout performance by increasing nitrogen retention and reducing fatigue. Some users experience 20–30% strength gains in compound lifts.

  • Joint & Injury Recovery: Promotes collagen synthesis, aiding tendon/ligament repair and reducing joint pain. Used by athletes to accelerate recovery from strains or surgeries.

  • No estrogen conversion (no gynecomastia).

  • Does not cause hair loss (no DHT conversion).

Though considered milder than steroids, MK-2866 may still cause:

  • Mild suppression of natural testosterone (usually reversible post-cycle).

  • Headaches or nausea in sensitive individuals.

  • Slight fatigue or lethargy.
